What this notice covers
Cookies and similar local-storage mechanisms used by calvrix.co. We use as few as the service genuinely needs and name them here so technical visitors can audit the claim. No advertising cookies, no third-party trackers, no fingerprinting.
The complete list
| Name | Set by | Type | Purpose | Lifetime |
|---|---|---|---|---|
| calvrix:theme | Calvrix (your browser's local storage) | Functional · consent-gated | Your selected theme (light, dark, or system) so the site renders the same way on each visit. Written only after you accept the preferences notice. | Persistent (until you clear site data) |
| calvrix:consent | Calvrix (your browser's local storage) | Functional · strictly necessary | Records whether you accepted or declined the preferences notice, so we do not show it on every page load. | Persistent (until you clear site data) |
| beacon.min.js (no cookie) | Cloudflare Web Analytics | Analytics · statistical purposes | Counts page views and load performance in aggregate. It sets no cookie and stores no identifier, and it does not identify you. Covered by the statistical-purposes exception in Schedule A1 to PECR, so it loads unless you refuse it with the switch at the top of this page. | No cookie or stored identifier |
| __cf_bm | Cloudflare (network) | Strictly necessary · security | Cloudflare bot mitigation. Identifies automated traffic targeting the site. Exempt from consent as strictly necessary under Schedule A1 to PECR. | 30 minutes (rolling) |
| cf_clearance | Cloudflare (network) | Strictly necessary · security | Set after passing a Cloudflare security challenge. Lets you continue without re-challenging on every request. Exempt from consent as strictly necessary under Schedule A1 to PECR. | 30 days |
What we do not use
- Google Analytics, Hotjar, Mixpanel, Segment, Fullstory, or any other behavioural analytics product.
- Facebook Pixel, LinkedIn Insight Tag, Google Ads conversion tags, or any advertising cookies.
- Cross-site tracking, browser fingerprinting, or device-ID enrichment services.
- Session-replay tools.
The traffic measurement we do use, Cloudflare Web Analytics, is cookieless and does not identify individual visitors. See the Privacy Policy for the lawful-basis analysis.
Your choices
- Accept on the preferences notice → your theme is remembered between visits, and analytics stays on.
- Decline on the preferences notice → the site still works; your theme follows the operating system preference for the session, and the analytics script does not load.
- Change your mind at any time → use the analytics switch at the top of this page. It takes effect immediately, with no need to clear site data.
- Clear site data in your browser also works: Calvrix treats the next visit as not-yet-answered.
- Strictly-necessary cookies (the Cloudflare network cookies above) cannot be declined, but they are not set for advertising or analytics and they expire on the schedule listed.
